Researchers found that the hippocampus expanded in subjects who were assigned to walk three times a week.
Most studies of exercise results rely on self-report of perceived benefits, which are often affected by bias on the part of the participant. This study is significant in that the results were obtained by studying brain scans, which revealed significant structural brain changes between the walkers and the yoga/resistance training control group. I do not see these results as a slam on yoga. Personally, yoga benefits me by strengthening my back and counteracting the normal effects of aging, particularly range of motion.
